It turns out that the climate control was NOT working. The Ford dealer had had the vehicle 3 times and deemed it ok but I still felt it wasnt right, I took it to a local a/c specialist and he confirmed it wasnt, he said that there was moisture in the system and it would at least require a new accumulator dryer and a orrofice tube. I took it back to the dealer with this info and they replaced the items, after which they phoned me and said 'my independant engineers assesment was incorrect, as it also needs a new compressor'. I bit my tongue and awaited further updates. They phoned again a few days later and said they also replaced a high pressure pick up tube and climate control module. I have now got the car back and it is certainly blowing out cold air. The new control module allows me to set the temperature between 16 and 29 degrees, the old module was 19 to 29 degrees. Whilst everything appears to be ok I have noticed that the light on the ac button is permanently illuminated, if I press it, it goes off but so does the 'auto' indicator in the display. Does anybody else out there have a modern Mondeo Ghia? and can you confirm if this is normal operation or not. Many thanks for any help or advise anyone can give. n.b The dealer declined to re-imburse me for independant engineers assesment.
